  Synthesis of a Non-Heme Template for Attaching Four Peptides:  An Approach to Artificial Iron(II)-Containing Peroxidases

  摘要：

  We are developing all-synthetic model cofactor-protein complexes in order to define the parameters controlling non-natural cofactor activity. The long-term objective is to establish the theoretical and practical basis for designing novel enzymes. A non-heme pentadentate ligand (N4Py) is being developed as a template for the site-specific attachment of a designed four-helix bundle. Previously, we attached two unprotected peptides via CH2Cl handles to N4Py. In the presence of hydrogen peroxide, the iron(II) complex of this ligand (2a) generates an (FeOOH)-O-III intermediate (3a) that can oxidize a wide variety of organic compounds. Here, we describe the synthesis of 27, a N4Py derivative in which four three-carbon spacers have been introduced, and show that four copies of an unprotected, single-cysteine peptide can be coupled via a thioether linkage to the ligand. In addition, a divergent synthesis route to tetrabromide ligand 1b has also been developed, providing the opportunity to prepare alternative pentadentate ligands efficiently by four cross-coupling reactions on a single molecule. Also, two of the four bromides of 1b can be selectively addressed by magnesium-bromide exchange.
